More Than High Temp. Tolerance! New Energy Vehicle Safety Upgrade: How Important is VTM V0 Class Flame-Retardant Labeling?Issuing time:2026-05-26 11:18 In the highly sophisticated and intelligent industrial system of modern automotive manufacturing, self-adhesive label materials have long transcended traditional identification functions. They have become essential foundational materials running through the entire lifecycle of automotive R&D, production, logistics, sales and after-sales services. Amid the explosive growth of the new energy vehicle (NEV) industry, self-adhesive labels are now subject to stringent safety requirements including flame retardancy, high temperature resistance, chemical corrosion resistance and high insulation. Their applications are extensive, and Changxin Adhesive’s product portfolio is illustrated in the figure below.
For label application details, please contact Business Manager Zhang Yao: yaozhang@changxinlabel.com I. Full-Scenario Penetration: Wide Application of Self-Adhesive Labels in the Automotive Industry1. Traditional Fuel Vehicles: Information Carriers for Harsh Operating Environments·Engine Compartment: PI (Polyimide) and high-temperature resistant PET labels withstand temperatures of 150-300℃ and engine oil corrosion, permanently marking VIN codes, part models and assembly parameters. ·Exterior & Interior Body: Regulatory warning labels, functional instructions and decorative decals feature UV resistance, friction resistance and anti-tampering performance, complying with regulatory standards and enhancing user experience. ·Production & Supply Chain: QR code and barcode traceability labels support lean production, quality control and full-process lifecycle tracking. 2. New Energy Vehicles: Core Defense Line for Flame-Retardant SafetyCentered on high-voltage batteries, electronic control systems and electric motors, NEVs face prominent risks of thermal runaway and electrical safety hazards. Fire and flame retardancy have become the primary threshold for label materials, generating new rigid market demands: ·Power Battery System: Labels for cells, modules, PACK enclosures and BMS mainboards must feature high temperature resistance, electrolyte corrosion resistance, superior flame retardancy and halogen-free low-smoke performance, preventing labels from becoming combustion accelerants during thermal runaway. ·High-Voltage Wiring & Electronic Control: Flame-retardant, insulating and heat-resistant labels mark voltage parameters, circuit loops and safety warnings to ensure high-voltage circuit safety. ·Passenger Compartment & Interior: Compliant with national standard GB 8410-2022, materials deliver low smoke, low toxicity and flame retardancy, reducing the release of toxic flue gas in case of fire.
II. New Rigid Demand for NEVs: Flame-Retardant Labels as the Bottom Line of SafetyWith the official implementation of GB 38031-2025 Safety Requirements for Traction Batteries of Electric Vehicles, NEV safety standards have been upgraded from the "5 minute escape rule" to the higher requirement of no fire and no explosion, revolutionizing material flame-retardant specifications.
1. Top-Grade Flame Retardancy Requirements High-risk components such as batteries, wiring harnesses and electronic control parts must meet UL94 VTM-0— the highest flame-retardant grade for thin film materials. Features include immediate self-extinguishing upon leaving the flame, no combustible dripping, extremely short combustion duration, and zero smoke toxicity.
2. Full-Structure Flame Retardancy The face material, adhesive layer and release liner all adopt full-system flame-retardant design, avoiding adhesive melting, label peeling and flame spread under high temperatures.
3. International Compliance & Market Access For exports to the EU and North America, products must pass VTM-0, RoHS and REACH certifications with halogen-free, eco-friendly, low-smoke and low-toxicity properties.
Flame-retardant labels are no longer an optional accessory — they have become the safety bottom line and market access passport for new energy vehicles. The test report of Changxin’s bright white PET VTM V0 material is shown in the figure.
Test Conclusion: The sample fully meets the requirements of UL94-2024 VTM-0. Remarks: The residual flame time and residual glow time were tested with the release liner removed from the sample. All test data are for scientific research, teaching, internal enterprise quality control and product R&D purposes only. No partial reproduction of this test report is permitted without written approval from CTI.
